متن کاملInvestigation of the production of free radicals in ultraviolet irradiation using SnO2:Eu nanoparticles
In studying the ultraviolet (UV) radiation, one of the important factors is the possibility of generating a variety of free radicals inside the body by these radiations. In this paper, a method of estimating the amount of hydroxyl radicals produced by ultraviolet rays was investigated using nanoparticles of tin oxide doped with uropium. In this method, the change in absorption intensity of meth...
متن کاملFree radicals in carcinogenesis.
It has become clear since the workshop that free radicals are implicated not only in the promotion phase of carcinogenesis but during initiation as well. Since the workshop, however, despite intriguing trapping studies with Superoxide disimilase. catalase, and Cu-DIPS [copper(II)(3,5-diisopropylsalicylate)2] and generation of OJ using xanthine oxidase, little substantive evidence has been obtai...
